一、銅版紙
I. Copperplate Paper
我們所說的銅版紙是在漂白木漿制成的原紙上涂上一層白色化學原料，再經過壓光而成。在紙的消費過程中有單面涂布壓光和雙面涂布壓光兩種，所以我們的銅版紙有單雙面之分。
What we call copperplate paper is made of bleached wood pulp coated with white chemicals and then calendered. In the process of paper consumption, there are two kinds: one-sided coated calendering and two-sided coated calendering, so our copperplate paper can be divided into one-sided and two-sided.
另外壓光面分為亮光和亞光兩種，在業界中簡稱光銅和亞粉，也就是打印社稱謂的“銅版紙"與“亞粉紙”之分，其實它們都是銅版紙。銅版紙的特性是紙張外表潤滑度和潔白度較高，厚薄平均分歧，伸縮性小，復原才能較強，且相對低價。
In addition, the calendering surface is divided into bright and matt, in the industry referred to as smooth copper and sub-powder, that is, printing agency Title "copper plate paper" and "sub-powder paper", in fact, they are copperplate paper. Copper plate paper is characterized by high surface lubricity and whiteness, average difference in thickness, small flexibility, strong recovery ability, and relatively low price.

亞粉紙在日光下察看，與光銅紙相比，不太反光。用它印刷的圖案，雖沒有銅版紙顏色鮮艷，但圖案比銅版紙更細膩，更。普通亞粉紙會比光銅紙薄并且白，愈加吃墨，并且比擬硬正，不像光銅紙很容易變形，覺得書頁不平整的書肯定是光銅紙。只要彩打才會用到亞粉紙，黑白的話就是光銅紙或膠版紙（即再生紙）。
The sub-powder paper looks in the sunlight, which is less reflective than the light copper paper. The pattern printed with it is more delicate and high-end than that printed with copperplate, although there is no bright color of copperplate paper. Ordinary sub-toner paper will be thinner and white than smooth copper paper, more ink-eating, and more rigid, unlike smooth copper paper, it is easy to deform, feel that books with uneven pages must be smooth copper paper. As long as the color printing will use sub-toner paper, black and white is light copper paper or offset paper (that is, recycled paper).
平常我們說的157、185等指的是銅版紙每的克重，市面上有70-350g/m2的銅版紙，習氣上300g/m2以上的稱為銅版卡。
Usually we say 157, 185, etc. refer to the weight of copperplate paper per square metre. There are 70-350g/m2 copperplate paper on the market, and more than 300g/m2 is called copperplate card.

二、膠版紙
2. Offset Paper
膠版紙是在漂白木漿制成的原紙外表施膠而成，對油墨吸收平均，紙張外表潤滑度、密度和印刷效果比銅版紙差一些。
Offset paper is made by sizing the surface of raw paper made from bleached wood pulp. It absorbs ink equally. The surface lubricity, density and printing effect of offset paper are worse than those of copperplate paper.

三、特種紙
III. Special Paper
特種紙也叫花式紙，由不同材質的原料制成，屬于裝飾用紙，紙的外表有的壓紋，有的經過特殊處置，由于材質和造紙工藝不同，特種紙品種繁多，顏色十分豐厚，是一些時髦前衛包裝、印刷品、書籍、畫冊為了突出設計效果經常采用的紙張，但價錢普遍高于普通紙張，包裝印刷時也要特別留意顏色復原方面問題。
Special paper is also called fancy paper, which is made of different materials. It belongs to decorative paper. Some of the paper's exterior embossed lines and some of them have been treated specially. Because of the different material and paper-making technology, there are many kinds of special paper with abundant colors. It is often used in fashionable avant-garde packaging, printing, books and picture albums to highlight the design effect, but the price is generally higher than that of ordinary paper. Paper, packaging and printing should also pay special attention to color restoration.
除了這紙張之外，還有凸版紙、白卡紙、新聞紙等等。
Besides this paper, there are letterpress, white cardboard, newsprint and so on.

四、開數
Four, open number
通常說的幾開就是把一張正度紙（787mm×1092mm）或者大度紙（889mm×1194mm）幾等分。規范未裁切的紙張稱為全開，對開就是一分為二，四開就是四等分，以此類推。市場上大局部快印公司選擇的是大度紙停止裁切。
Generally speaking, the opening is to divide a positive paper (787mm * 1092mm) or a large paper (889mm * 1194mm) into several equal parts. Standard uncut paper is called full open, opposite is divided into two, four is divided into four, and so on. Most fast printing companies in the market choose to stop cutting large paper.
